Description

本発明は、学校の校舎などに用いて好適な建築構造に関する。   The present invention relates to an architectural structure suitable for use in a school building or the like of a school.

従来、学校の校舎などの施設においては、天井高さを3.0m(あるいはそれ以上)にし、建物の内部に極力広い空間を確保することが求められる(例えば、特許文献1、特許文献2、特許文献3、特許文献4参照)。   Conventionally, in facilities such as a school building of a school, it is required to make the ceiling height 3.0 m (or more) and secure a wide space as much as possible inside the building (for example, patent documents 1, patent documents 2, Patent Document 3 and Patent Document 4).

そして、これを実現するために、大スパン、大階高、例えば、7m×7m×9m程度の標準柱スパン、4m程度の階高にして架構構造(建築構造)を設計・構築するようにしている。   And, in order to realize this, design and build a frame structure (architectural structure) with a large span, a large floor height, for example, a standard column span of about 7m x 7m x 9m, and a floor height of about 4m. There is.

一方、市街地の狭小敷地において、3階建校舎を建築する場合には、階高が4m程度であると建物高さが10mを超えることから、日影規制の適用を受ける。これにより、建築構造が複雑なセットバックを伴う形態の構造になり、さらにこのセットバックを伴う建物形態になることに起因して、学校施設としてのフレキシビリティの確保が困難になってしまうケースが多々ある。   On the other hand, when building a three-story school building in a small area in a city area, the building height exceeds 10 m if the floor height is about 4 m, so the application of shading control is applied. As a result, the building structure becomes a structure with a complicated setback, and there are cases where it becomes difficult to secure flexibility as a school facility due to the formation of a building with this setback. There are many.

上記事情に鑑み、本発明は、所望の天井高さを確保しつつ極力低階高にし、低階高でありながら大スパンを実現して広い無柱空間を確保することを可能にする建築構造を提供することを目的とする。   In view of the above circumstances, the present invention is an architectural structure that makes it possible to secure a desired ceiling height as much as possible and to realize a large span and secure a large non-pillared space while maintaining a low floor height. Intended to provide.

上記の目的を達するために、この発明は以下の手段を提供している。   In order to achieve the above object, the present invention provides the following means.

本発明の建築構造は、鉄骨造の建築構造であって、建物外周側に耐震要素を配置し、建物外周側の大梁よりも建物中央側を通る大梁の梁成を小さくし、上階スラブの裏面に接して天井材を配置することによって天井高さが確保されており、前記上階スラブの裏面に接して前記天井材を配置することによって天井高さを確保した室の空調を行うための空調設備が、他の室の天井空間の内部、及び/又は壁の内部に集約配置されていることを特徴とする。 The building structure of the present invention is a steel-framed building structure, in which aseismic elements are disposed on the outer periphery of the building, the beam formation of large beams passing through the center side of the building is smaller than the large beams on the outer periphery of the building , and A ceiling height is secured by arranging a ceiling material in contact with the back surface, and for performing air conditioning of a room whose ceiling height is ensured by arranging the ceiling material in contact with the back surface of the upper floor slab It is characterized in that the air conditioning equipment is intensively disposed inside the ceiling space of the other room and / or inside the wall .

この発明においては、建物外周側にブレースなどの耐震要素を配置することによって、建物中央側を通る大梁の梁成を小さくすることができ、且つ小さな梁成の大梁で大スパンを実現することができる。これにより、建物中央側に低階高でありながら所望の天井高さを確保することが可能になるとともに、広い無柱空間を形成することが可能になる。   In this invention, the beam formation of the large beam passing through the center side of the building can be reduced by disposing seismic elements such as braces on the outer peripheral side of the building, and a large span can be realized with the large beam having a small beam size. it can. As a result, it is possible to secure a desired ceiling height while maintaining a low floor height on the central side of the building, and it is also possible to form a wide non-columnar space.

また、二重天井を適用せず、上階スラブの裏面に吸音材などの天井材を取り付けることによって、例えば、3.2m程度の低階高でありながら3.0m程度の天井高さを実現することが可能になる。 Also , by applying a ceiling material such as a sound absorbing material to the back of the upper floor slab without applying a double ceiling, for example, a ceiling height of about 3.0 m is achieved while the floor height is about 3.2 m. It will be possible to

さらに、二重天井を適用せず、上階スラブの裏面に吸音材などの天井材を取り付けて低階高で所望の天井高さを確保するようにした場合であっても、この部屋の空調を、他の室の天井空間の内部、及び/又は壁の内部に集約配置した空調設備で行うことが可能になる。 Furthermore , even if a double ceiling is not applied and a ceiling material such as a sound absorbing material is attached to the back of the upper floor slab to secure a desired ceiling height at a low floor height, air conditioning of this room It can be performed with the air conditioning equipment arranged centrally in the ceiling space of the other room and / or the inside of the wall.

また、本発明の建築構造においては、建物のファサードには耐震要素としてブレース又は斜柱が用いられていることがさらに望ましい。   Further, in the building structure of the present invention, it is further desirable that a brace or a diagonal pillar be used as a seismic element in the facade of the building.

この発明においては、建物外周に耐震要素を配置するようにした場合に、建物のファサードの耐震要素としてブレース又は斜柱を用いることで、見栄えをよくすることができる。   In the present invention, when the seismic elements are arranged around the building, the appearance can be improved by using a brace or a diagonal column as a seismic element of the facade of the building.

本発明の建築構造によれば、建物外周に耐震要素を配置することによって、大梁の梁成を600mm程度にすることができ、3階建てで10m未満にした建物、すなわち、階高を3.2m程度の低階高にして日影制限を受けない建物を実現することができる。   According to the building structure of the present invention, by arranging the aseismatic elements on the outer periphery of the building, it is possible to make the girder structure of the large girder about 600 mm, and a three-story building less than 10 m, ie, the floor height 3. It is possible to realize a building that is not subject to the shadow restriction by making the height as low as 2m.

これにより、建物高さが10mを超えて日影制限を受けた場合のようにセットバックを伴う建物形態にする必要がなく、全ての階で、整形の使いやすい平面計画を実現することが可能になる。   As a result, it is possible to realize an easy-to-use plan plan of shaping on all floors, without having to be in the form of a building with setback as in the case of a building height exceeding 10 m and being subjected to shadow restrictions. become.

また、建物中央側を通る大梁の梁成を小さくしたり、従来の二重天井を採用せず、上階スラブ裏面に天井材を取り付けて天井面を形成するなどすることによって、天井高さ3.0mを確保することができる。   In addition, the ceiling height 3 can be achieved by reducing the beam formation of large beams passing through the center of the building or by using a conventional double ceiling and attaching a ceiling material to the back of the upper floor slab to form a ceiling surface. .0 m can be secured.

これにより、このように低階高でありながら十分な天井高さを確保するとともに、梁成の小さな大梁を用いて大スパン、ひいては例えば300mを超える無柱空間を実現できる。よって、建物内スペースの利用の自由度を大幅に高めることができ、例えば将来の間仕切り改修などに対応しやすい建物にすることができる。 As a result, it is possible to secure a sufficient ceiling height despite such a low floor height, and to realize a large span, that is, a non-columnar space exceeding 300 m 2, for example, by using a large cross beam. Therefore, the degree of freedom in using the space in the building can be greatly enhanced, and for example, it can be a building that can easily cope with partition improvement and the like in the future.

And, a large span can be realized by the large beam 4 with a small beam structure. As a result, it is possible to secure a desired ceiling height while maintaining a low floor height on the central side of the building, and it is also possible to form a wide non-columnar space.

また、二重天井を適用せず、上階スラブの裏面に吸音材などの天井材2を取り付けることによって、例えば、3.2m程度の低階高でありながら3.0m程度の天井高さを実現することが可能になる。   In addition, by applying a ceiling material 2 such as a sound absorbing material to the back of the upper floor slab without applying a double ceiling, for example, a ceiling height of about 3.0 m while having a low floor height of about 3.2 m It will be possible to realize.

さらに、二重天井を適用せず、上階スラブの裏面に吸音材などの天井材2を取り付けて低階高で所望の天井高さを確保するようにした場合であっても、この室の空調を、他の室の天井空間の内部、及び/又は壁の内部に集約配置した空調設備3で行うことが可能になる。   Furthermore, even if a double ceiling is not applied and a ceiling material 2 such as a sound absorbing material is attached to the back of the upper floor slab to secure a desired ceiling height with a low floor height, It becomes possible to perform the air conditioning with the air conditioning equipment 3 centrally arranged inside the ceiling space of another room and / or inside the wall.

また、建物外周に耐震要素1を配置するようにした場合に、建物のファサードの耐震要素1としてブレース又は斜柱を用いることで、見栄えをよくすることができる。   Moreover, when the seismic resistance element 1 is arrange | positioned around a building, appearance can be improved by using a brace or a diagonal pillar as the seismic resistance element 1 of the facade of a building.

したがって、本実施形態の建築構造Aによれば、建物外周に耐震要素1を配置することによって、大梁4の梁成を600mm程度にすることができ、3階建てで10m未満にした建物、すなわち、階高を3.2m程度の低階高にして日影制限を受けない建物を実現することができる。   Therefore, according to the building structure A of the present embodiment, by arranging the aseismatic elements 1 on the outer periphery of the building, the girder structure of the girder 4 can be made about 600 mm, and a three-story building less than 10 m, ie The floor height can be as low as 3.2m to realize a building that is not subject to shadow restrictions.

これにより、建物高さが10mを超えて日影制限を受けた場合のようにセットバックを伴う建物形態にする必要がなく、全ての階で、整形の使いやすい平面計画を実現することが可能になる。   As a result, it is possible to realize an easy-to-use plan plan of shaping on all floors, without having to be in the form of a building with setback as in the case of a building height exceeding 10 m and being subjected to shadow restrictions. become.

また、建物中央側を通る大梁4の梁成を小さくしたり、従来の二重天井を採用せず、上階スラブ裏面に天井材2を取り付けて天井面を形成するなどすることによって、天井高さ3.0mを確保することができる。   In addition, the height of the ceiling can be achieved by reducing the beam formation of the girder 4 passing through the center of the building or by using the ceiling material 2 by attaching the ceiling material 2 to the back of the upper floor slab without adopting the conventional double ceiling. It is possible to secure 3.0m.

これにより、このように低階高でありながら十分な天井高さを確保するとともに、梁成の小さな大梁4を用いて大スパン、ひいては例えば300mを超える無柱空間を実現できる。よって、建物内スペースの利用の自由度を大幅に高めることができ、例えば将来の間仕切り改修などに対応しやすい建物にすることができる。 As a result, it is possible to secure a sufficient ceiling height despite such a low floor height, and to realize a large span, that is, a pillar-free space exceeding 300 m 2, for example, by using the large girder 4 with a small beam structure. Therefore, the degree of freedom in using the space in the building can be greatly enhanced, and for example, it can be a building that can easily cope with partition improvement and the like in the future.
